I have Plusnet FTTP. Recently I bought the Google Nest WiFi router and point. When I tried to connect I received an error saying VLAN logging is not supported. After a fair bit of searching forums and trial and error I solved this by installing an Ethernet switch between the Modem (box on the wall for FTTP) and the Google Router. The old Plusnet Hub is now removed. All is working well now. I now have two Ethernet switches to allow me to hardwire the TV and a couple of hubs to the google router as it only has one LAN port. I used TP link TL-SG1008D.
